辽宁省海岸线长达二千六百公里,沿海滩涂广阔,港湾甚多,为对虾养殖提供了十分优越的条件,仅丹东地区养虾面积已达九万五千多亩,总产对虾四千余吨,占全国首位。近二年由于养对虾的面积迅速扩大,天然饵料严重不足,去年天然兰给每公斤高达0.44元,但还经常买不到,人工饵料又没发展起来,逼着养虾场喂大米饭、明台鱼等。因此,对虾普遍长得又瘦又小,全市区对虾养殖大面积减产,平均亩产仅为53.3公斤,致使多数对虾养殖场亏本。所以,研究和生产对虾人工配合饵料已成为当务之急。
Liaoning Province coastline up to 2,600 kilometers, a vast beach along the coast, a lot of bays for shrimp farming provides a very favorable condition, only Dandong shrimp area has reached 95,000 mu, more than four thousand shrimp production Ton, accounting for the first place in the country. The past two years due to the rapid expansion of shrimp area, a serious shortage of natural food, natural blue last year, up to 0.44 yuan per kilogram, but often can not buy, artificial food has not developed, forcing shrimp farm to feed rice Ming Taiwan fish. Therefore, shrimp generally grow thin and small, the city’s large area shrimp farming cut, the average yield of only 53.3 kg, resulting in the loss of most shrimp farms. Therefore, the study and production of artificial bait with shrimp has become a top priority.
